What is the purpose of a manual shut-off valve?

The purpose of a manual shut-off valve is to completely shut off the gas supply. This type of valve is a critical safety feature in gas systems, enabling the user to halt the flow of gas quickly and effectively in the event of an emergency, maintenance, or when a system is not in use. It ensures that there are no leaks or accidental gas flow when needed, reducing the risk of hazardous situations.

Manual shut-off valves are typically located at key points in the gas line, such as before appliances or at the main supply, making them easily accessible for immediate action. Proper operation and maintenance of these valves are essential to ensure a safe working environment. While there are other valves and devices designed for regulating gas flow, measuring pressure, or analyzing gas composition, the fundamental role of a manual shut-off valve is to completely stop the gas supply, making it a vital component in gas systems for safety management.
